Yeah,
So, if you had one of these cheaper refractors without nibnobs sticking out everyplace, and you were a bit suspicious of the optical alignment, what could you do?
Now you might say, "sell it", but that's a begging the question a bit. Are there any really advanced techniques like bending the OTA over your knee?
I suppose that we here would have to be really brave to take out the primary lens and pack it a bit this way or that, but what would a well qualified techo do in the case where one of these scopes showed up a star test which was not the best? Someone with an optical bench I mean.
Cheers
